PIC16F877A在新型质子旋进磁力仪中的应用

Application of PIC16F877A in the New-style Proton-precession Magnetometer

受制于当时微电子技术的发展,传统质子磁力仪存在电路复杂、元器件分立过多等不足之处,在确保观测原理不变的情况下,选取PIC16F877A作为主控芯片应用于新型质子旋进磁力仪中。介绍了整体的硬软件设计,同时与加拿大GEM公司生产的DiDd三分量磁力仪测量数据进行比较,结果显示在测量精度及准确度上两者非常接近,新型质子旋力进磁仪具有很好的稳定性和抗干扰性,达到了预期的效果。

Restricted to the development of microelectronics technology at that time, the traditional proton magnetometer has some disadvantages such as complicated circuits, more isolated components etc. When the observation principle is unchanged, we use the PIC16F877A as the main control chip of the new proton precession magnetometer. The article describes its overall hardware and software design, at the mean while, compares it with DiDd three-component magnetometer produced by Canadian GEM in measurement data. The result shows that they are very close in the measurement precision and accuracy, and the new proton precession magnetometer we design has good stability and anti-jamming, and achieves the desired results.
